I have following text in a file
23456789
When i tried to replace the above text using command
1,$s/\(\d\)\(\d\d\d\)\(\d\d\)*\>/\3\g
I am getting 89. Should't it be 6789? Can anyone tell me why it is 89.

If this…

I am writing a tool to help students learn regular expressions. I will probably be writing it in Java.
The idea is this: the student types in a regular expression and the tool shows which parts of a text will get matched by the regex. Simple enough.
But I want to support several different regex…

I'm writing a piece of client-side javascript code that takes a function and finds the derivative of it, however, the regex that's supposed to match with the power rule fails to work in the context of the javascript program, even though it sucessfully matches when it's used with an independent regex…

I need to be able to check for a pattern with | in them. For example an expression like d*|*t should return true for a string like "dtest|test".
I'm no regex hero so I just tried a couple of things, like:
Regex Pattern = new Regex("s*\|*d"); //unable to build because of single backslash
Regex Pattern…

Like many of you, my custom Vim configuration is stored in my ~/.vimrc, with the plugins, colors, etc. stored under ~/.vim/plugins, ~/.vim/colors, etc.
I want to share a single Vim configuration among many servers. Some of these servers run Vim 7, some run the older Vim 6. Most Vim plugins are intended…

When I do
:echo &runtimepath

The "matchit" plugin for vim is supposed to allow you to use the % key to jump between matching start/end tags when editing HTML, as well as /* and */ comment delimiters when editing other kinds of code.
I've followed the exact instructions in ":help matchit", but % still doesn't work for me.
It…

I store, commands found at http://www.commandlinefu.com/commands/browse, in a text file.
If I open this text file in Vim and I want to execute the command where the cursor is actually located I do copy the line with Y, switching to command mode with : and !CTRL+r*
Is there a more "lazy" possibility ;)
